Hyperkalemia t wave change

WebThe T wave on the ECG is the positive deflection after the QRS complex. It represents the repolarization of the ventricular myocardium. To understand the T wave, let’s first briefly go over depolarization and repolarization. Both of these processes represent a shift in the electrical potential and ions of the cells. WebHypokalaemia is defined as a serum potassium level of < 3.5 mmol/L. ECG changes generally do not manifest until there is a moderate degree of hypokalaemia (2.5-2.9 mmol/L). The earliest ECG manifestation of hypokalaemia is a decrease in T wave amplitude. ECG features of hypokalaemia (K < 2.7 mmol/L)
